Extractions: Georg von PEURBACH Matemático e astrônomo austríaco nascido em Peurbach (perto de Viena), em 30de maio de 1423 e faleceu em 8 de abril de 1461 Peurbach estudou na Universidade de Viena e viajou depois para a Itália, então o centro intelectual da Europa. Ali encontrou Nicolau de Cusa. Voltou para Viena em 1453 e aí ensinou matemática e astronomia. recebendo o cargo de astrônomo real do rei da Hungria. Peurbach era defensor ardente do uso dos algarismos arábicos, inovação velha de 250 anos, importada por Fibonacci. Mesmo assim, a numeração romana, muito inferior. continuava sendo obstinadamente usada, notável exemplo de conservacionismo autodestruidor. Peurbach usou os algarismos arábicos para elaborar uma tabela de senos, de precisão ímpar, e aperfeiçoou a mecânica da trigonometria muito além do ponto atingido pelos gregos e pelos árabes, tornando a vida dos reacionários muito difícil. Contudo, morreu antes de concluir sua obra. Seu aluno. Regiomontanus, trabalhou na elaboração da mesma tabela e também morreu antes de terminá-la. Peurbach tentou melhorar o sistema ptolomaico. mas não ousou alterar sua essência. Deu até um passo atrás, insistindo na sólida realidade das esferas cristalinas dos planetas. ponto pouco desenvolvido pelo próprio Ptolomeu no

One of the major publications of Renaissance natural philosophy, the Epitome of Ptolemy's Almagest appears; the authors, Georg Peurbach (1423-1461) and Johannes Regiomontanus (1436-1476), symbolize a shift from reverence for Ptolemy and antiquity to respect coupled with confident innovation. Publication of the highly influential Corpus Hermeticum , a collection of writings (we now know) to have been written in the early Christian era but then thought to have been written with great authority by Hermes Trismegistus (perhaps Thoth or Moses) living c.1800 BC. Georg Peurbach's New Theory of the Planets (1454) sought to reconcile geometric descriptive models for predicting planetary motions by employing homocentric (nested concentric) celestial spheres.

Extractions: One of the most powerful creations of Greek science was the mathematical astronomy created by Hipparchus in the second century B.C. and given final form by Ptolemy in the second century A.D. Ptolemy's work was known in the Middle Ages through imperfect Latin versions. In fifteenth-century Italy, however, it was brought back to life. George Trebizond, a Cretan emigre in the curia, produced a new translation and commentary. These proved imperfect and aroused much heated criticism. But a German astronomer, Johannes Regiomontanus, a protege of the brilliant Greek churchman Cardinal Bessarion, came to Italy with his patron, learned Greek, and produced a full-scale "Epitome" of Ptolemy's work from which most astronomers learned their art for the next century and more. Copernicus was only one of the celebrities of the Scientific Revolution whose work rested in large part on the study of ancient science carried out in fifteenth-century Italy.

Extractions: This is a lovely copy, bound in full contemporary very dark Italian morocco over wooden boards, tooled in blind, and very well preserved. The original bosses and clasps were very carefully removed at a relatively early date, which is barely a defect in that it exposes some lovely tooling that would otherwise have been obscured. The binding was rebacked long ago, and the work retains the character of the original. A very early paper label is pasted on the back board.

Extractions: Personalities Tour (Next) Previous Regiomontanus Tour (Next) Regiomontanus Pages General Pages Home Index Regiomontanus (1436-1476) was born in Konigsberg and educated at Leipzig and Vienna. He sought to restore astronomy, dissatisfied as he was with the inadequate translation of ancient works and the disparities he found between theory and observation. His Epitome of the Almagest was published in 1496. Frontispiece of Regiomontanus' Epitome of the Almagest depicting Ptolemy and Regiomontanus sitting beneath an armillary sphere.

This work was finished by 1463, and printed as the Epitome of the Almagest in 1496; it was later used by such astronomers as Copernicus and Galileo In Vienna, Regiomontanus had been an avid hunter, copyist, and reader of manuscripts on mathematical and astronomical subjects. After Peurbach's death, he went with Bessarion to Rome, and accompanied him on various travels around Italy. Association with the Cardinal, a native of Trebizond in Turkey and a great patron of humanist scholarship, gave Regiomontanus access to other texts, and the opportunity for him to become fluent in Greek. On several occasions, he was to forcefully express his opinion about the inadequacy of translations of Greek works, including Ptolemy's

Extractions: Books Tour (Next) Previous Books Pages Early Modern Books Copernicus Galileo Kepler ... Previous Regiomontanus Pages Regiomontanus Astrology Calendar Reform Mathematical Techniques ... Index When he moved to Nuremberg in 1571, Regiomontanus embarked, as part of his strategy for the reformation of astronomy, on a program of publication. The first work issued by his press was the Theoricae novae planetarum of his former master Georg Peurbach, which rapidly became one of the standard texts of university courses in astronomy. This was followed by the Astronomica of Marcus Manilius, his calendars in Latin and German for 1475-1531, and almanacs for 1485-1506. In 1474, he published a broadside tradelist naming both the books he had already printed and those he still intended to produce. Works by Ptolemy , Euclid, Theon of Alexandria, Archimedes, and Witelo were among those listed, as were many new translations, commentaries and treatises by Regiomontanus himself. Criticism of the lack of respect this list revealed for other authors and translators prompted him, in his pamphlet Disputationes contra Cremonensia in planetarum theoricas delyramenta (or Arguments against the nonsense in the Theorica planetarum of [Gerard of] Cremona), to deliver a trenchant defence of the necessity of emending and improving upon existing texts:

Extractions: The first speculations about the possibility of the Sun being the center of the cosmos and the Earth being one of the planets going around it go back to the third century BCE. In his Sand-Reckoner , Archimedes (d. 212 BCE), discusses how to express very large numbers. As an example he chooses the question as to how many grains of sand there are in the cosmos. And in order to make the problem more difficult, he chooses not the geocentric cosmos generally accepted at the time, but the heliocentric cosmos proposed by Aristarchus of Samos (ca. 310-230 BCE), which would have to be many times larger because of the lack of observable stellar parallax. We know, therefore, that already in Hellenistic times thinkers were at least toying with this notion, and because of its mention in Archimedes's book Aristarchus's speculation was well-known in Europe beginning in the High Middle Ages but not seriously entertained until Copernicus. European learning was based on the Greek sources that had been passed down, and cosmological and astronomical thought were based on Aristotle and Ptolemy.

On the second orbit Leonov left the spacecraft through the air lock while still tethered to the vessel. He took motion pictures and practiced moving outside of the spacecraft for 10 minutes. Voskhod 2 made 17 orbits at about 110 miles (177 km) above earth. Ten years later, on 17 Jul 1975, Leonov commanded the Soviet Soyuz craft that linked in orbit with a U.S. Apollo craft.

Extractions: Gary Boyle , the Observers Group Chair, opened the last meeting of the Ottawa Centre of the 1900s with the comment, "Well, folks, they lost another one!" He was referring, of course, to the sad loss of NASAs Mars Polar Lander probe . During the time of the meeting, hope was still alive that contact would eventually be made, but alas, twas not to be. Moving on to exciting news, Gary also spoke of how astronomers gathered more evidence of extra-solar planets by measuring a 1.7% drop in a stars light as a suspected planet moved in front of it relative to Earth. It seems that the Galaxy is indeed teeming with planets. What a fitting end to the 1900s! Paul Comision was our usual first speaker of the month to present his latest Cutting Edge of Astronomy topic. Paul discussed the "bottom-up" theories about how galaxies are formed through collisions and mergers of smaller galaxies (much like how pile-ups are formed on Ottawa highways during freezing rain), as opposed to the older "top-down" theories where a galaxy is born a specific size and stays that way throughout its life, and how the bottom-up theories were gaining prominence. The December 1999 issue of Astronomy magazine covered this topic in detail.
